@J12t @activitypubtestsuite Perhaps an obvious answer but: Which tools out there are ActivityPub standard (federation, not client) compliant (I’d consider that 1 thing, since it’s binary).
In more detail: Which of the different ActivityStreams verb and noun pairs are supported by each tool, split out across client - server, and server - server protocols.
@philip @activitypubtestsuite how would you define “supported”?
